REMOVABLE COVER.

Specification of Letters' Patent.

Patented Oct. 15, 1907.

- Application tiled September 4,1906. Serial No. 833,137.

which the following isa spccilication.

My invention relates to improvements in books and removable covers therefor and the art of making the same. p l My invention relates more particularly to the means l'or detachably securing removable 4portions of a book and to the art el producing said means.

The object ol' my invention is to produce a book oi this class which shall be simple and effective in its construction and operation and especially one which shall be capable of giving long service and withstanding rough usage. 'I

My object is further to provide a novel method whereby booksof this class may be made economically and uniformly,

My invention consists in providing a novel form of stud and a novel means for securing the stud to the cover oi' a book for the purpose. of holding looselcaves and the like, such as blank checks, which have previously been perforated to receive the studs.

My invention consists further in a novel method for forming the holding means by which the 4stud is secured to the cover.

In the drawings accompanying and forming a part of this specilication, Figure 1 is a section of a book embodying my invention; Fig. 2 is a section showing the manner of placing the stud in the cover preparatory to4 its being secured therein; Fig. 3 is a view showing the method of assembling the stud and washer with the board which forms part of the cover, preparatory to forming the flange upon the stud to hold the washer in place; Fig. 4 is a sectional View corresponding to Fig. 3 showing the parts after said operation is perfumed.

The reference characters are used in the same sense throughout the drawings and the specifications.

Numeral 1 represents the board l'orming part of the cover of a book; 2 represents a block of checks or other leavesprovded with perforations adapted to receive the stud 3; 4 is a nut on the stud 3 which holds the block of leaves 2 in place. The stud 3 is provided with a head 5, preferably made integrally with the stud, a body portion 6 of less diameter than the head, a llange or enlargement 7 of greater diameter than the body portion, a reduced cylindrical portion 8 adjacent to the flange 7, whose diameter is less than that oi the body portion and equal to or greater than that. of the threaded extension 9. Between the head and the flange is a Washer l0 of greater diameter than the flange. '30th the head 5 and the washer 10 are preferably embedded in the board l so that their outer sunaces are flush with the surfaces ol said board. It is preferable to have the stud secured to the board belore the covering material l1 is put onto the covers 1 so that the head and the washer shall not be exposed.

Hcretofore it has been the practice in books of this class, to form a shoulder intermediate the ends of the stud, which shoulder would correspond in position to the washer 10, and then to form somekind of a head on than the strain which would be produced by forcing the stud down through the board. By means of my construction it will be seen that the head 5 may be proportioned to have adequate strength for any use, at the same time thel flange 7 has abundant strength to hold the stud rigidly in position.

The method I employ in carrying out my invention is as follows: Studs are formed in the manner shown in Figs. 2 and 3, having a head 5 and body portion 6 and a threaded end 9, the body portion being somewhat larger in diameter than the threaded end 9. A punch or die 12, having a central bore 13 adapted to pass over the threaded end 9, preferably somewhat greater in diameter than the threaded end, but of a diameter smaller than the body portion 6, is then driven or forced down over the stud in such a way as to form the ilange.7 by its shearing or crushing action. The punch during this operation is forced far enough to embed the head 5 and the washer 10 into the board 1 as far as desired.

Having thus described my invention, what I claim is:

1. A stud havnga head, a body portion of I ess diameter than said head, a flange formed integrally on said body portion. a threaded extension beyond said body portion of less diameter. and a washer between said flange and said head.

than said head, a flange formed upon said body portion of greater diameter, and an extension of said body portion beyond snd ilange having a less diameter', than said body portion. and a Washer between said flange and said head,

2i. A binding post or stud having a head, a body portion adjacent to and of less diameter than said head, a Iiange on said body portion, an extension of less diameter than said body portion and a washer between said head and said flange.

4. A stud having a head, a body portion of less diameter than said head, a flange upon said body portion and an ex. tension of less diameter than said body portion.

2. A stud having; a head, a body portionof less diameter- 5. A binding post for removable covers having a head, a body portion adjacent to the head, an extension of less diameter than said body portion Vand a flange formed upon said body portion by forcing over it a die of less diameter than said body portion. I

6. The art of securing a washer to a binding post which consists lin forcing a die of less diameter than the body portion of the binding post over said body portion against said washer, thereby producing n flange or projection upon 10 said body portion adjacent to said Washer.

7. The art of forming a retaining ange upon a stud or binding post having n body portion and an extension of less diameter than said body portion, which consists in forcing'a die, having un openingr of less diameter than said body portion adapted to receive said extension, over suid extension upon said body portion.

In testimony whereof, I have signed my nnmc to this speciiication in the presence of two subscribing,r witnesses. MARK H. BERRY. Witnesses C. A. CANTON, ERNEST MILLER.
